42
Q

Definition of Silo?

A

Storage tank for research in discipline isolated from other disciplines

43
Q

Definition of Plasticity?

A

refers to the brain’s ability to change and adapt as a result of experience

44
Q

Plasticity denotes two complementary aspects of development. What are they?

A

– Human traits can be molded.

– People maintain a certain durability of identity.

45
Q

Dynamic systems

A

– Human development is viewed as an ongoing, ever-changing interaction.
• Between the physical and emotional being
• Between the person and every aspect of his or her environment, including the family and society

46
Q

what is the characteristic multidirectional?

A

change occurs in every direction, not always in a straight line. gains and losses, predictable growth, unexpected transformations are evident

47
Q

what is the characteristic multidisciplinary?

A

numerous academic fields – especially psychology, biology, education, and sociology, but also neuroscience, economics, religion, anthropology, history, medicine, genetics, and many more – contribute insights

48
Q

what is the characteristic multi contextual?

A

human lives are embedded in many contexts, including historical, conditions, economic constraints, and family patterns

49
Q

what is the characteristic multicultural?

A

many cultures – not just between nations but also within them – affect how people develop

50
Q

what is the characteristic plasticity?

A

every individual, and every trait within each individual, can be altered at any point in the life span. Change is ongoing, although it is neither random not easy

51
Q

A
  1. multidirectional
  2. multidisciplinary
  3. multicontextual

52
Q

what does scientific observation require?

A

requires the research to record behaviour systematically and objectively

53
Q

definition of effect size?

A

a quantitative measure of the magnitude of the experimental effect. The larger the effect size the stronger the relationship between two variables.

54
Q

definition of significance?

A

a relationship between two or more variables is caused by something other than chance

55
Q

definition of odds ratio?

A

represents the odds that an outcome will occur given a particular exposure, compared to the odds of the outcome occurring in the absence of that exposure.

56
Q

definition of factor analysis?

A

a way to take a mass of data and shrinking it to a smaller data set that is more manageable and more understandable. It’s a way to find hidden patterns, show how those patterns overlap and show what characteristics are seen in multiple patterns.

57
Q

definition of meta-analysis?

A

a research process used to systematically synthesise or merge the findings of single, independent studies, using statistical methods to calculate an overall or ‘absolute’ effect.

58
Q

what does effect size indicate?

A

Indicates how much one variable affects another. Effect size ranges from 0 to 1: An effect size of 0.2 is called small, 0.5 moderate, and 0.8 large.

59
Q

what does significant indicate?

A

Indicates whether the results might have occurred by chance. If chance would produce the results only 5 times in 100, that is significant at the 0.05 level, once in 100 times is 0.01; once in 1,000 is 0.001.

60
Q

what does odds ratio indicate?

A

Indicates how a particular variable compares to a standard, set at 1. For example, one study found that, although less than 1 percent of all child homicides occurred at school, the odds were similar for public and private schools. The odds of it in high schools, however, were 18.47 times that of elementary or middle schools (set at 1.0) (MMWR, January 18, 2008).

61
Q

what is the independent variable?

A

Variable that is introduced to see what effect it has on the dependent variable

62
Q

what is the dependent variable?

A

Variable that may change as a result of whatever new condition or situation the experimenter adds

63
Q

What is wrong with this study?
Professor Jones wants to study vocabulary growth in preschool children. He contacts
all of his faculty colleagues who have children, and from this group, he assembles a sample of 20 faculty children ranging from two to five years of age. To test each child’s word knowledge, Professor Jones reads each child a list of simple words that he has gathered from children’s storybooks and records whether or not the child understands each word. He then uses the results to publish norms (standard or expected levels of achievement) for vocabulary mastery for each year from two to five years of age.

a) no control group
b) biased or non-representative sample
c) interpreting a correlation as indicating cause and effect
d) experimenter bias (experimenters’ expectations influence the results)
e) participant bias (participants’ expectations influence the results)

A

b) biased or non-representative sample

Professor Jones tested only the children of college professors. This limited group is an example of a biased or non-representative sample.

The genetic inheritance and environmental experiences of faculty children could differ from those of the general population in important ways that would influence the rate of language development.

64
Q

What’s wrong with this study?

Professor Okamoto is interested in the effects of prosocial TV on sharing behavior among preschool children. For clarification, prosocial actions are meant to benefit others rather than oneself. She assembles a sample of 100 children and then assigns each child at random to either the prosocial TV group or the neutral TV group.
The prosocial TV group views 30 minutes of TV with a prosocial theme while the neutral group views 30 minutes of TV with a neutral theme. After the children finish their TV session, Professor Okamoto assigns them to “play groups” of five children from the same TV group. She observes the small groups at play and rates each child on the tendency to share toys with other children.

a) no control group
b) biased or non-representative sample
c) interpreting a correlation as indicating cause and effect
d) experimenter bias (experimenters’ expectations influence the results
e) participant bias (participants’ expectations influence the results)

A

d) experimenter bias (experimenters’ expectations influence the results

The major flaw in this study is the fact that while Professor Okamoto did assign children randomly to the prosocial or neutral groups, she was actively involved in putting children into their play groups as well as observing their behaviours.

This is an example of a possible experimenter bias because Professor Okamoto’s knowledge of the type of television that each child had watched might influence her ratings of each child’s behaviour.

65
Q

What wrong with this study?

Professor Knudsen wanted to test the effect of a new method of second language instruction for young adults speaking only one language. He introduced the new method in all three of his spring semester German classes. At the end of the semester, he averaged the student grades. Since the overall class average was a B, he concluded that the new method enhanced acquisition of the second language.

a) no control group
b) biased or non-representative sample
c) interpreting a correlation as indicating cause and effect
d) experimenter bias (experimenters’ expectations influence the results
e) participant bias (participants’ expectations influence the results)

A

a) no control group

The major flaw in this study is lack of a control group. Professor Knudsen administered the new teaching method to all his students so there is absolutely no way to tell whether his method made any difference in his students’ acquisition of the second language.

Without a comparison group, we do not know whether a B average is better or worse than student performance under Professor Knudsen’s old teaching method or even under alternative teaching methods used by other instructors.

66

71
Q

What does a positive correlation mean?

A

both variables tend to increase or decrease

72
Q

What does a negative correlation mean?

one variable tends to increase while the other decreases

73
